Trailing Stop Loss Dual Moving Average Strategy

Overview

This strategy uses fast and slow moving average crossovers to determine long and short positions. It goes long when the fast MA crosses over the slow MA and closes position when the fast MA crosses below the slow MA. To pursue higher profits, the strategy adopts a trailing stop loss mechanism. Instead of setting the stop loss price right below the entry price after opening long positions, it sets a trailing stop loss price which moves up following the price rise until the price drop hits the stop loss price limit.

How it works

The strategy uses fast and slow Simple Moving Average (SMA) lines to determine entries and exits. When the fast SMA crosses over the slow SMA, it signals an uptrend so the strategy goes long. When the fast SMA crosses below the slow SMA, it signals a trend reversal so the strategy prepares to close position.

To maximize profits, the strategy introduces a trailing stop loss mechanism. Instead of using a fixed stop loss price after opening long positions, it sets a trailing stop loss price which moves up following the price rise. Each time the price rises by a certain percentage, the trailing stop loss price adjusts up by a predefined percentage. When the price pulls back and hits the trailing stop loss price, it triggers the stop loss order to close position.

Specifically, the trailing stop loss price is calculated as:

Trailing Stop Loss Price = Price × (1 - Stop Loss Trailing Percentage)

The Stop Loss Trailing Percentage is defined by the strategy parameter “Deviation %”. The strategy recalculates the trailing stop loss price on every bar’s close. The new trailing stop loss price cannot be lower than that of the previous bar, so as to ensure the stop loss price only moves up, not down.

When the price drops and hits the trailing stop loss price, it triggers the closing signal and the position will be closed by a market order.

Advantages

Use dual moving average to determine trend direction with good backtest results
Adopt trailing stop loss to pursue higher profits
Customizable moving average periods and stop loss trailing percentage
Stop loss line keeps moving up when trend goes up, locking in most profits
Quick stop loss when trend reverses to avoid further losses

Risks and Solutions

Improper moving average crossover timing may cause false signals. Test different parameters to find the optimal MA combination
Overly aggressive trailing stop loss may get stopped out prematurely. Adjust the stop loss trailing percentage parameter properly
Price gaps may directly penetrate the stop loss price. Consider combining other indicators to judge trend and avoid trading during ranging periods

Optimization Directions

Test different moving average period parameters to find the optimal combination
Test different stop loss trailing percentage parameters to find the optimal stop loss level
Add other indicators to suspend trading during ranging periods to avoid being affected by sporadic events

Conclusion

This strategy combines moving average indicators to judge trend direction and trailing stop loss mechanism to lock in profits, performing well on training data. By optimizing parameters and controlling risks, it has the potential to achieve steady profits. However, no strategy can completely avoid losses. It’s recommended to adjust position sizing, test different products, and diversify risks.

//  Description
//  =============================================================================
//  This strategy will go long if fast MA crosses over slow MA.
//  If the 'Enable Trailing` is checked then the strategy instead of exiting from the position
//  directly it will follow the price upwards (percentagewise) with small steps
//  If the price drops by this percentage then the exit order will be executed
//
//  The strategy has the following parameters:
//
//  Fast SMA Length - How many candles back to calculte the fast SMA.
//  Slow SMA Length - How many candles back to calculte the slow SMA.
//  Enable Trailing - Enable or disable the trailing
//  Deviation % - The step to follow the price when the open position condition is met.
//  Source Exit Control - The source price to compare with the exit price to trigger the exit order when trailing.
